SCORING MECHANISM FOR CARDBOARD AND SIMILAR MATERIAL.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed November 10, 1915. Serial No. 60,655.

To all whom, it may concern:

Be it known that I, OSCAR C. Ronsnn, J12, a citizen of the United States, residing at New York city, county of Kings, and State of New York, have invented certain new and useful Improvements in Scoring Mechanism for, Cardboard and Similar Materials, fully described and represented in the following specification and the accompanying. drawings, forming a part of the same.

This invention relates to certain improvements in machines for creasing or scoring cardboard and similar materials in which a plurality of parallel creases or scores are given the sheet of material.

In machines heretofore used for forming a plurality of creases or scores parallel, with or longitudinal to the run of the sheet, a plurality of creasing wheelswere employed set in line with each other. This arrangement put board operated upon due to the pull'of the creasing devices and caused frequent breaks and cracks in the material.

It is the object of the present invention to produce a machine for producing a plurality of parallel creases or scores in cardboard or similar sheet material which shall prevent this cracking or breaking of the material.

For a full understanding of the invention, reference may be had to the accompanying drawings, in which the figure is a perspective view of so much of a creasing or scoring machine as is necessary for an understanding of the invention.

Referring to the drawing, the cardboard or other material which, as shown, is ,of

sheet form, is fed to the machine from a suitable feed-board or table provided with the usual front stops 2 for registering the sheet.

In machines embodying the invention there will be provided a support against which the sheet is creased. In the preferred construction this support will be a carrier which carries the sheet around past suitable creasing devices. While the construction of this carrier may be varied, in the particular construction illustrated it is a cylinder 3 having .a hard surface against which the sheet is creased or scored. When the carrier is. a cylinder it is or may be provided with sheet-taking devices, which in the present instance are grippers 4:, which a strain on the fibers of the'cardare or may be mounted so as to have a slight.

movement longitudinally of or across the cylinder to compensate for any tendency of the sheet to move across the cylinder while being creased, these grippers being operated in any usual or desired manner.

For giving the creases or scores longitudinally of the run of the sheet, creasing devices are employed which may vary somewhat in construction. They will be of such character, however, that two or more parallel creases or scores will begiven the sheet longitudinally thereof, that is, in adirection running around the cylinder and on lines at right angles to the axis thereof, and. to prevent the breaking or cracking of the sheet material in this scoring operation these creasing devices will be positioned in staggered'relation with each other longitudinally of the cylinder, so that one such device forms a crease or score ahead of the a next succeeding one as the sheet is presented to the creasers by the rotation of the cylinder. In the particular construction shown, these scoring devices comprise rotatable wheels or disks 5 suitably mounted to give the requisite creasing pressure, as on shafts 6 mounted adjacent the cylinder.

As shown, there are provided three shafts. each carrying two wheels or disks, though of course the number of creasers may be varied to produce the desired number of creases. If desired, for dividing large sheets, a slitter may be employed of any usual or desired construction, such as a slitting wheel 7 suitably mounted in slitting relation with the cylinder, as on a shaft 8. Suitable holding guides are or may also be provided for holding the sheet in position on the cylinder, as guide fingers 9 mounted on a rod 10.

Transverse creases or scores, that is, scores widewise of the sheet, or in a direction par- -allel with the axis of the cylinder, may be given the sheet to complete the scoring. In the best constructions these transverse creases will be made after the longitudinal creases have been made, and this can be conveniently done, as shown, by providing a reciprocating bed 11 cooperating with the cylinder and reciprocating beneath the same, this bed being driven in any usual or desired manner, and provided with the required number of creasing devices, which may be in the form of blunt rules 12, which act to crease or score the sheet as it is rotated by the cylinder, after having been so creased or scored longitudinally.

While the invention has been shown and described in its preferred form, it will be understood that it is not to be limited to the use of a cylinder forsupporting the sheet, but that other supporting surfaces may be employed Without departing from the 'invention. I

What is claimed is:

1.' In a machine of the class described, the combination of'a rotary sheet carrier provided with sheet-taking devices and having a supporting surface against which the material is creased, a plurality of creasing devices mounted in staggered relation to each other longitudinally of'the carrier for creasing the material in lines at right angles to the axis of the carrier, and means for creasing the material in lines parallel to the axis of the carrier.

2. In a machine of theclass described, the combination of a rotary sheet carrierprovided with sheet-taki1ig devices and having a supporting surface against which the material is creased, of means for dividing a sheet of material, and a plurality-of creasing devices mounted in staggered relation to each other longitudinally of thecarrier'on each side of the dividing means for producing a plurality of creases in each sheet in lines at right angles to the axis of the carrier.

3. In a machine of the class described, the

' combination of a sheet carrying cylinder having a supporting surface and provided with grippers, and a plurality of creasing Wheels or disks mounted to press against the cylinder and in staggered relation to ac other longitudinally of the cylinder.

4. In a machine of the class described, the combination of a sheet carrying cylinder provided With grippers, a plurality of creasing Wheels or disks mounted to press against the cylinder and in staggered relation to each other longitudinally of the cyl1nder,a

bed also cooperating with the cylinder, and
